5. Katy Perry – Obsessively Brushes Her Teeth
Katy Perry likes to keep her teeth pearly white and perfect. In fact, she has become quite obsessive about it. She is said to carry at least 20 toothbrushes on her at all times, so that she can brush her teeth whenever they feel dirty. She brushes them at least 6 times a day. It seems pretty obsessive, but at the same time we bet she’s never had a cavity!
